Forgot my PDF password? Any free way to open the file on a Windows 11 PC?

Ollsoweign  There is an free program called PDCrack that can help you if you forgot PDF password.  It is an open-source, command-line utility designed for recovering passwords from PDF files that are encrypted. It primarily works by employing a brute-force attack to guess the password. It can handle both user passwords (those required to open the document) and owner passwords (those that restrict permissions for editing or printing the PDF).  

To open password forgot PDF file on a Windows 11 PC, you first need to download the tool from its official website or a trusted repository. Once downloaded, you must extract the files, typically using a file compression tool. Open Command Prompt, navigate to the directory where PDCrack is located using the "cd" command, and then run the program using the command "pdcrack yourfile.pdf", replacing "yourfile.pdf" with the name of your locked PDF file.

As it starts running, it will begin attempting to recover the password through various combinations. Depending on the complexity of the password and your computer's processing power, this could take anywhere from a few minutes to several hours, or even longer. It’s advisable to be patient and monitor its progress through the command line.
